BEARING FOR SVPINDLES.

SPECIFICATION forming part of Letters Patent N0. 729,460, dated May 26, 1903. firiginal application filed April 12, 1901, Serial No. 55,514. Divided and this application filed July 17, 1901. Serial To all whom it may concern.-

Be it known that I, THOMAS WATSON, a subject of the King of Great Britain and Ireland, and a resident of Bridgeof-Weir, in the county of Renfrew, Scotland, have invented a certain Improved Bearing for Spindles, of which the following is a specification.

My said invention has for its object to improve the construction of bearings for spin- IO dles, my improved bearing being especially applicable to spindles used in spinning and doubling machinery. e

My improved bearing is shown in the accompanying sheet of drawings, in which Figure l is a vertical section, Figs. 2 and 3 being, respectively, a plan and an elevation of details.

The spindle of the drawingsis one adapted to be revolved by flier means concentric therewith and has no pulley.

I do not wish to confine myself to the use of any particular construction of flier means; but I may employ those disclosed in my Patent No. 708,945, dated September 9, 1902, the

combination being illustrated in Fig. 2 of my Patent No. 691,991, granted January 28, 1902, upon an application of which this application is a division.

As shown in the drawings, the spindle 3 is fitted to rotate in a bolster-case 28, the bolster-case being fixed to a movable rail 29 of the machine. The lower end of the spindle 3 rotates in a footstep bearing 30, formed within a bolster 31. The body of the spindle 5 fits loosely in the bolster 31, which also fits loosely in the bolster case 28, being kept from turning by a key 32, Fig. 2, in its upper end engaging in a groove 33 in the bolster-case. The upper end of the bolster is 0 formed with a curved shoulder part, which engages in a countersunk socket within the upper end of thebolster-ease. Oil for lubrieating is admitted to the foot-step bearing 30 by means-of grooves 34: and holes 35, formed in the bolster 31, the oil being afterward discharged through slots 36 into the lower part 37 of the bolster-case.

By resting the spindle on its foot-step in the foot-step bearingand fitting it looselythrou gh- (No model.)

out its length in the bolster and by mounting the bolster at its upper end, so as to be free to swing in any direction, I produce an extremely easy running spindle that will adapt itself to the slightest change of tension of the thread and one that can gyrate freely. A hood or hollow shoulder part 38, formed on the spindle 3, fits overthe upper end of the bolster-case 28, and a look 39 for the spindle 3 is fixed to the side otthe bolster-case by means of a screw-pin '40, the upper end 41 of the locking-piece being bent over, so as to engage on top of the shoulder on the spindle. The locking device thus prevents the spindle from being raised out of the bolster-case 28 when the cop is'being drawn off the spindle. 6 5

I claim as my invention 1. In bearings forspindles adapted to be revolved by flier means, the combination with a bolster-case of abolster having a foot-step bearing, a spindle mounted in said foot-step bearing but fitting loosely in the bolster in which it is entirely'free to gyrate on its footstep, the bolster being 'also fitted loosely in the bolster-case and having at its upperend a curved shoulder part, a countersunk socket within the upper end of the bolster-case,with which the curvedshoulder engages, and a key in the curved shoulder-part engaging in a groove in the bolster-case, substantially as described. I

2. In bearings for spindles adapted to be revolved by flier means, the combination with a bolster-case of a bolster fitting loosely in the case and having a foot-step bearing,a spindle mounted in said foot-step bearing, but entirely free to gyrate in the bolster onits footstep, the bolster having at its upper end a curved shoulder part, by which it is hung within the bolster-case, and means'toprevent the rotation of the bolster, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

THOMAS WATSON.
